Question

在Orchard 1.51中，我正在尝试从“管理自定义表单”界面添加新的自定义表单（当前不存在任何表单）。我得到一个空引用异常。这类似于Cowboy Hell上个月发生的错误Orchard Create Featured Items Error。他跟进并关闭了这个问题：“数据库中存在问题。我删除它后再次部署它就可以了。”

听到这个消息我并不感到惊讶，但我有一个网站有很多内容和配置。我没有使用迁移来对数据库进行版本控制。该网站开始使用Orchard的版本，并已成功推出。

我一直在尝试添加“自定义表单”。禁用和重新启用自定义窗体模块不起作用。我没有看到任何干净的方法来完全从项目中删除它并重新添加它。我可以从文件系统中删除该模块，并删除一个专门引用自定义表单Orchard_CustomForms_CustomFormPartRecord的数据库表，但这让我很紧张。
